Why single rear carriers?• Replaces frame bottle: Standard frame-mounted bottles have high aerodynamic drag, so place your bottle at the rear instead. The DELTAs are mounted on the saddle rails for no measurable drag.
• Refills front drink system: Use the DELTAs to refill a front drink system. Just bring the spare bottle forward from the DELTA and refill. If you have the popular XLAB TORPEDO aerobar mounted system (sold separately), then simply replace the empty front bottle with the spare bottle from the DELTA.
• Adds an extra bottle: These systems are also ideal for longer training rides or century rides, where an extra bottle is necessary so you can have your favorite mix with you at all times.
